Impact of Oophorectomy on Survival and Improving Nutritional Status in Ovarian Metastasis from Colorectal Adenocarcinoma.

INTRODUCTION: Ovarian metastasis of colorectal cancer is known to have a poor prognosis. This study aimed to elucidate the characteristics of patients who underwent oophorectomy for ovarian metastasis from colorectal cancer. METHODS: This retrospective study included 16 patients who underwent oophorectomy for colorectal cancer metastasis to the ovary from January 2004 to December 2017. Improvement in patient's symptoms and pre- and postoperative changes in various nutritional and inflammatory indicators were assessed. Survival analysis and identification of prognostic factors were conducted with a median follow-up of 40.7 (5-109) months. RESULTS: Of 16 patients, 12 had (75%) synchronous and 4 (25%) had metachronous metastasis. Fourteen patients were symptomatic but symptoms resolved postoperatively. Thirteen patients (81.3%) had ascites and 5 (31.3%) had pleural effusion on preoperative computed tomography that disappeared after surgery in all cases. The median value of prognostic nutritional factor was significantly increased postoperatively (36.0 [preoperatively] vs. 47.5, p < 0.0001). The median (interquartile range) values for lymphocyte-C-reactive protein ratio were 715.2 (110-2,607) preoperatively and 6,095.2 (1,612.3-14,431.8) postoperatively (p = 0.0214). The median survival of the entire cohort was 60.4 months. The 3-year survival rates for R0 + R1 and R2 cases were 83% and 24% (p = 0.018), respectively. Univariate analysis showed that R2 resection and low postoperative lymphocyte-C-reactive protein ratio were associated with poor prognosis. CONCLUSIONS: Oophorectomy for ovarian metastasis from colorectal cancers was safely performed. It improved the patients' symptoms and nutritional status and may result in improved prognosis.

Lymphocyte to C-reactive protein ratio could better predict the prognosis of patients with stage IV cancer.

BACKGROUND: Systemic inflammation is currently regarded as a hallmark of cancer. This study aimed to accurately clarify the prognostic value of various inflammatory markers in patients with stage IV cancer. METHODS: This study assessed 2,424 patients with cancer diagnosed with cancer in tumor, node, metastasis (TNM) stage IV. After evaluating the predictive value of 13 inflammatory indicators for patient prognosis using the C index, the lymphocyte C-reactive protein ratio (LCR) was selected to elucidate the prognostic and predictive values in patients with stage IV cancer. Kaplan-Meier and Cox proportional hazards regression models were used to analyze long-term survival. RESULTS: A total of 1,457 men (60.1%) and 967 women (39.9%) diagnosed with TNM stage IV cancer were enrolled. A ratio of 2,814 was defined as the optimal cut-off value for the LCR. The LCR was the most accurate prognosis predictor for patients with stage IV cancer among the 13 inflammatory nutritional markers evaluated. The multivariate-adjusted restricted cubic spline plot suggested that LCR had an L-shaped dose-response association with all-cause mortality risk. Patients with lower LCR levels tended to present with worse prognoses. Kaplan-Meier curves and log-rank test results showed that the high LCR groups (LCR ≥ 2,814) exhibited a better prognosis, whereas patients with stage IV cancer of different sex and tumor types (for example, gastrointestinal tumor, non-gastrointestinal tumor, and lung cancer) had a worse survival time. CONCLUSION: The LCR score can be regarded as a stable and useful biomarker to predict prognosis in patients with TNM stage IV compared to other evaluated inflammation indicators.

Lymphocyte-C-reactive protein ratio as a novel prognostic index in intrahepatic cholangiocarcinoma: A multicentre cohort study.

BACKGROUND & AIMS: The lymphocyte-C-reactive protein ratio (LCR) is a novel inflammatory-based score, based solely on the lymphocyte and C-reactive protein. We aimed to clarify the prognostic value of the LCR score in intrahepatic cholangiocarcinoma (ICC) patients after resection. METHODS: We compared the prognostic accuracy of the LCR score with other inflammatory-based scores in this large, multicentre cohort study. The independent variables associated with overall survival (OS) were explored in both the primary (n = 228) and validation cohorts (n = 135). Harrell's concordance index (C-index) was used to compare the predictive ability of all the assessed inflammatory-based scores. RESULTS: The LCR score was differentiated two groups of ICC patients with distinct prognoses (1-, 3-, and 5-year OS rates: 94.4%, 66.3%, and 59.3%; and 66.6%, 45.6%, and 32.7%, respectively) (P < .001). Multivariate analysis showed that the LCR score, as well as the TNM stage and preoperative CA19-9 level, were independently associated with OS. The predictive accuracy of the LCR score (c score: 0.634) was superior to that of the other inflammatory-based scores (c scores: 0.508-0.615). These findings were supported by the external validation cohort. CONCLUSION: The LCR score is stable and consistently the best prognostic score and may offer as a simple, objective and discriminatory method in facilitating the risk stratification of ICC patients.

Preoperative lymphocyte/C-reactive protein ratio and its correlation with CD8+ tumor-infiltrating lymphocytes as a predictor of prognosis after resection of intrahepatic cholangiocarcinoma.

PURPOSE: To clarify whether the preoperative lymphocyte/C-reactive protein (CRP) ratio (LCR) is a prognostic factor for patients with intrahepatic cholangiocarcinoma (IHCC), and investigate its mechanism via tumor-infiltrating lymphocytes. METHODS: The subjects of this retrospective study were 42 patients who had undergone hepatectomy for IHCC. We divided the patients into low LCR and high LCR groups (cutoff value: 8780) and analyzed their overall survival (OS) and disease-free survival (DFS) with respect to LCR and other clinicopathological factors. We also investigated the levels of stromal tumor-infiltrating lymphocytes (TILs) and CD8+ TILs in surgical specimens, and the relationship between LCR and TILs. RESULTS: A low LCR was identified in 21 patients and was significantly correlated with older age, a high CRP-albumin ratio, and advanced disease stage, and was a prognostic factor for OS and DFS. Multivariate analysis revealed that a low LCR was an independent prognostic factor for worse OS (HR 10.40, P = 0.0077). Although the LCR and levels of stromal TILs were not significantly related, LCR and levels of CD8+ TILs were significantly related (P = 0.0297). CONCLUSION: The preoperative LCR may predict the postsurgical prognosis of patients with IHCC and reflect the CD8+ TILs.

Cumulative perioperative lymphocyte/C-reactive protein ratio as a predictor of the long-term outcomes of patients with colorectal cancer.

PURPOSE: Systemic inflammatory response influences cancer development and perioperative surgical stress can affect the survival of patients with colorectal cancer (CRC). We developed a system to cumulatively assess perioperative inflammatory response and compare the prognostic value of various cumulative inflammatory and nutritional markers in patients with CRC. METHODS: We assessed perioperative cumulative markers using the trapezoidal area method in 307 patients who underwent surgery for CRC and analyzed the results statistically. RESULTS: The cumulative lymphocyte to C-reactive protein (CRP) ratio (LCR) predicted survival more accurately than other well-established markers (sensitivity: 80.0%, specificity: 69.3%; area under the curve (AUC): 0.779; P < 0.001). A low cumulative LCR was correlated with factors associated with disease development, including undifferentiated histology, advanced T stage, lymph node metastasis, distant metastasis, and advanced TNM stage classification. A decreased cumulative LCR was an independent prognostic factor for both overall survival (OS) (Hazard Ratio (HR):5.21, 95% confidence interval [CI] 2.42-11.2; P < 0.0001) and disease-free survival (DFS) (HR: 1.88, 95% CI 1.07-3.31; P = 0.02), and its prognostic significance was verified in a different clinical setting. The cumulative LCR was correlated negatively with the intraoperative bleeding volume (P < 0.0001, R = -0.4). Combined analysis of cumulative and preoperative LCR could help stratify risk for the oncological outcomes of CRC patients. CONCLUSIONS: The findings of this study demonstrate the value of the cumulative LCR in the postoperative management of patients with CRC.

Clinical implications of the preoperative lymphocyte C-reactive protein ratio in esophageal cancer patients.

PURPOSE: We recently revealed the preoperative lymphocyte C-reactive protein ratio (LCR) to be a new marker for predicting various outcomes in malignancies. The aim of our present study was to clarify the potential utility of the preoperative LCR for predicting the perioperative risk and oncological outcome in esophageal cancer patients. METHODS: We analyzed the preoperative LCR from 153 esophageal cancer patients to clarify its clinical relevance. RESULTS: The preoperative LCR was significantly decreased in a stage-dependent manner, and a decreased preoperative LCR was significantly associated with the occurrence of postoperative surgical site infection. Esophageal cancer patients with a low LCR showed a poor outcome in both the overall survival and disease-free survival compared with those who had a high LCR. Multivariate analyses showed that a decreased LCR was an independent prognostic factor for both a poor overall survival and disease-free survival. A decreased preoperative LCR was an independent predictive factor for postoperative surgical site infection and significantly correlated with nutritional and inflammatory indicators. In addition, the LCR was useful for identifying esophageal cancer patients likely to have a poor outcome among patients with and without neoadjuvant chemotherapy. CONCLUSIONS: Assessing the preoperative LCR might help physicians identify populations at high risk for perioperative complication and oncological outcomes, and determine individualized perioperative therapeutic strategies.

Prognostic value of lymphocyte-to-C-reactive protein ratio in patients with gastric cancer after surgery: a multicentre study.

OBJECTIVE: The immune inflammation-based score is recognized as a prognostic marker for cancer. However, the most accurate prognostic marker for patients with gastric cancer remains undetermined. We aimed to evaluate the predictive value of the lymphocyte-to-C-reactive protein ratio for outcomes in gastric cancer patients after radical gastrectomy. METHODS: A total of 607 gastric cancer patients treated at three Chinese institutions were included. Receiver operating characteristic curves were generated, and the areas under the curve were calculated to compare the predictive value among the inflammation-based score, lymphocyte-to-C-reactive protein ratio, C-reactive protein/albumin and neutrophil-lymphocyte, platelet-lymphocyte and lymphocyte-monocyte ratios. Cox regression was performed to determine the prognostic factors for overall survival. RESULTS: The median follow-up time was 63 months (range: 1-84 months). The optimal cut-off value for lymphocyte-to-C-reactive protein ratio was 0.63. The patients were divided into the LCR <0.63 (LLCR, n = 294) group and the LCR ≥0.63 (HLCR, n = 313) group. LLCR was significantly correlated with poor clinical characteristics. Compared with inflammation-based score, lymphocyte-to-C-reactive protein ratio had the highest areas under the curve (0.695). Patients with LLCR experienced more post-operative complications than the HLCR group (20.4 vs. 12.1%, P = 0.006). Multivariate analysis showed that a higher lymphocyte-to-C-reactive protein ratio (HR: 0.545, 95%CI: 0.372-0.799, P = 0.002) was associated with better overall survival. The HLCR group had higher 5-year overall survival rate than the LLCR group (80.5 vs. 54.9%, P < 0.001). CONCLUSIONS: Preoperative lymphocyte-to-C-reactive protein ratio levels can effectively predict the short-term and oncological efficacy of gastric cancer patients after radical gastrectomy with a predictive value significantly better than other inflammation-based score.

Lymphocyte-C-reactive protein ratio combined with albumin upon admission predicts coronary artery dilation and aneurysm formation in pediatric patients with Kawasaki disease: a retrospective cohort study.

BACKGROUND: We aimed to explore simple and effective clinical parameters or combinations to predict coronary artery dilation and aneurysm formation in pediatric patients with Kawasaki disease (KD). DESIGN AND METHODS: This retrospective cohort study included pediatric patients with KD from January, 2013 to December, 2022. Multiple demographic and clinical data were collected, collated, and calculated from the medical records. Then they were divided into the coronary artery dilation and aneurysm formation group or the non-coronary artery dilation and aneurysm formation group. Lymphocyte-C-reactive protein ratio (LCR) was transformed into its natural logarithm and expressed as lnLCR. RESULTS: A total of 64 pediatric patients with KD were enrolled in this cohort study after 1:3 propensity score matching (PSM). For each unit increase in lnLCR, the possibility of coronary artery dilation and aneurysm formation decreased to 0.419 times the original value. The areas under the receiver operating characteristic (ROC) curves of lnLCR combined with albumin (ALB), ALB, and lnLCR to classify pediatric patients with KD into the coronary artery dilation and aneurysm formation group were 0.781, 0.692, and 0.743, respectively. CONCLUSION: LCR combined with ALB upon admission is a promising predictor of coronary artery dilation and aneurysm formation in pediatric patients with KD.

The Impact of Hematologic Parameters on Histopathologic Features of Colorectal Cancer.

Background: Colorectal cancers (CRC) are one of the most common tumors that are being researched for new biomarkers worldwide. In this context, studies are being carried out to estimate whether various hematological parameters can be used for predicting prognosis. In this study, our aim was to evaluate the relation between platelet (PLT) levels as well as neutrophil-to-lymphocyte ratio (NLR), platelet (PLT)-to-lymphocyte ratio (PLR), and Lymphocyte-to-CRP ratio (LCR) which are easily accessible inflammatory response indicators. Methods: In this retrospective cross-sectional study, 111 patients diagnosed as colorectal adenocarcinoma were included. Patients with clinical evidence of an infection, recurrent colorectal cancer, previous history of a hematological disease, and a neoadjuvant chemo/radiotherapy were excluded. Demographic features such as age, gender, and histopathologic parameters such as tumor size, surgical margin status (proximal, distal, and radial), the presence of serosal inflammation, lymphovascular invasion (LVI), perineural invasion (PNI), lymph node metastasis (LNM) and distant metastasis, preoperative blood sample analysis, and CRP levels were noted. Statistical analysis for the association between hematologic parameters platelet (PLT) levels as well as neutrophil-to-lymphocyte ratio (NLR), platelet (PLT)-to-lymphocyte ratio (PLR), and Lymphocyte-to-CRP ratio (LCR) and histopathological features were done. Results: Among 111 patients, the mean age was 65.37, and the mean tumor size was 5.41 cm. Lymphovascular invasion, perineural invasion, radial surgical margin positivity, lymph node metastasis, localization, and stage were statistically significantly related to the number of platelets. For NLR, PNI (p=0.001), LNM (p=0.048), and stage (early/advanced) (p=0.045) were significantly related. None of the parameters were related to PLR and LCR. Conclusion: Perineural invasion, lymph node metastasis, and the stage of the tumor could be the major histopathological features that could be related to hematologic parameters; however, this should be researched by larger studies as if they can be used as prognostic markers.

Dynamic lymphocyte-CRP ratio as a predictor: a single-centre retrospective study on disease severity and progression in adult COVID-19 patients.

OBJECTIVE: To assess the efficacy of dynamic changes in lymphocyte-C-reactive protein ratio (LCR) on differentiating disease severity and predicting disease progression in adult patients with Coronavirus disease 2019 (COVID-19). METHODS: This single-centre retrospective study enrolled adult COVID-19 patients categorized into moderate, severe and critical groups according to the Diagnosis and Treatment of New Coronavirus Pneumonia (ninth edition). Demographic and clinical data were collected. LCR and sequential organ failure assessment (SOFA) score were calculated. Lymphocyte count and C-reactive protein (CRP) levels were monitored on up to four occasions. Disease severity was determined concurrently with each LCR measurement. RESULTS: This study included 145 patients assigned to moderate (n = 105), severe (n = 33) and critical groups (n = 7). On admission, significant differences were observed among different disease severity groups including age, comorbidities, neutrophil proportion, lymphocyte count and proportion, D-Dimer, albumin, total bilirubin, direct bilirubin, indirect bilirubin, CRP and SOFA score. Dynamic changes in LCR showed significant differences across different disease severity groups at different times, which were significantly inversely correlated with disease severity of COVID-19, with correlation coefficients of -0.564, -0.548, -0.550 and -0.429 at four different times. CONCLUSION: Dynamic changes in LCR can effectively differentiate disease severity and predict disease progression in adult COVID-19 patients.

Lymphocyte-to-C Reactive Protein Ratio is an Independent Predictor of Survival Benefits for Hepatocellular Carcinoma Patients Receiving Radiotherapy.

Background: Stereotactic body radiotherapy (SBRT) has emerged as an alternative approach for patients with hepatocellular carcinoma (HCC), and we aim to find potential prognostic biomarkers for HCC patients who received SBRT. Methods: In this study, we retrospectively analyzed HCC patients who underwent SBRT in our institution from January 2018 to December 2022. The inflammatory parameters, along with baseline patients' characteristics were collected to elucidate the potential relationship with survival benefits and liver toxicities. Results: Overall, 35 patients were enrolled in our study. For the efficacy population (25 patients who underwent SBRT for primary liver lesions), the objective response rate (ORR) and disease control rate (DCR) were 60% and 100%, respectively. The median progression-free survival (PFS) was 9.9 months [95% confidence interval (CI) 5.6-14.1 months], and the median overall survival (OS) was 18.5 months (95% CI 14.2-22.8 months). We further confirmed that higher baseline lymphocyte-C-reactive protein ratio (LCR) (≥2361.11) was positively related to both longer PFS (12.0 vs 4.3 months, P = 0.002) and OS (21.9 vs 11.4 months, P = 0.022). Moreover, patients with diabetes and higher alpha-fetoprotein (AFP) (≥400 ng/mL) were also found to be associated with worse OS. The most common hepatotoxicity was elevated gamma-glutamyl transferase (GGT) (84.0%). Conclusion: In conclusion, for patients with inoperable HCC, SBRT resulted in satisfactory local control, survival benefits, and acceptable liver toxicity. Pre-radiotherapy LCR might be an independent and readily available predictor for survival, which facilitates us to find the most appropriate treatment options.

Predictive and Prognostic Potentials of Lymphocyte-C-Reactive Protein Ratio Upon Hospitalization in Adult Patients with Acute Pancreatitis.

Purpose: In this study, our objective was to investigate the potential utility of lymphocyte-C-reactive protein ratio (LCR) as a predictor of disease progression and a screening tool for intensive care unit (ICU) admission in adult patients with acute pancreatitis (AP). Methods: We included a total of 217 adult patients with AP who were admitted to the First Affiliated Hospital of Harbin Medical University between July 2019 and June 2022. These patients were categorized into three groups: mild AP (MAP), moderately severe AP (MSAP), and severe AP (SAP), based on the presence and duration of organ dysfunction. Various demographic and clinical data were collected and compared among different disease severity groups. Results: Height, diabetes, lymphocyte count (LYMPH), lymphocyte percentage (LYM%), platelet count (PLT), D-Dimer, albumin (ALB), blood urea nitrogen (BUN), serum creatinine (SCr), glucose (GLU), calcium ion (Ca2+), C-reactive protein (CRP), procalcitonin (PCT), hospitalization duration, ICU admission, need for BP, LCR, sequential organ failure assessment (SOFA) score, bedside index for severity in AP (BISAP) score, and modified Marshall score showed significant differences across different disease severity groups upon hospitalization. Notably, there were significant differences in LCR between the MAP group and the MSAP and SAP combined group, and the MAP and MSAP combined group and the SAP group, and adult AP patients with ICU admission and those without ICU admission upon hospitalization. Conclusion: In summary, LCR upon hospitalization can be utilized as a simple and reliable predictor of disease progression and a screening tool for ICU admission in adult patients with AP.

Lymphocyte-to-C-reactive protein ratio as a new biomarker for predicting mortality and morbidity in Fournier's gangrene.

OBJECTIVE: The purpose of this study was to research the neutrophil-lymphocyte ratio (NLR), lymphocyte-to-C-reactive protein ratio (LCR), and Fournier's Gangrene Severity Index (FGSI) for predicting prognosis and mortality in patients with Fournier's gangrene (FG). MATERIAL AND METHODS: Patients diagnosed with FG and treated in a tertiary referral hospital in the period from January 2013 to June 2020 were reviewed. LCR, FGSI, and NLR values were calculated. RESULTS: Our series included a total of 41 patients. Of the patients, 78% survived and 21.9% (n = 9) died. Survivors were significantly younger than non-survivors (p = 0.009). Hospital costs were higher in non-survivors and close to statistical significance (p = 0.08). The ROC analysis revealed that the FGSI, LCR, and NLR parameters were significant in identifying survivors and non-survivors (AUC = 0.941 [0.870-1.000], p < 0.001; AUC = 0.747 [0.593-0.900], p = 0.025; and AUC = 0.724 [0.548-0.900], p = 0.042). CONCLUSION: A low LCR value can be used as a marker to assess mortality and disease severity in patients with Fournier's gangrene.

OBJETIVO: Investigar el cociente neutrófilos-linfocitos (CNL), el cociente linfocitos-proteína C reactiva (CLP) y el índice de gravedad de la gangrena de Fournier (IGGF) para predecir el pronóstico y la mortalidad en pacientes con gangrena de Fournier (GF). MÉTODO: Se revisaron los pacientes diagnosticados de GF y atendidos en un hospital de tercer nivel de referencia en el período de enero de 2013 a junio de 2020. Se calcularon los valores de CLP, IGGF y CNL. RESULTADOS: Nuestra serie incluyó 41 pacientes, de los cuales el 78% sobrevivieron y el 21.9% (n = 9) fallecieron. Los supervivientes eran significativamente más jóvenes que los no supervivientes (p = 0.009). Los costes hospitalarios fueron mayores en los no supervivientes y cercanos a la significación estadística (p = 0.08). El análisis ROC reveló que los parámetros IGGF, CLP y CNL fueron significativos para identificar supervivientes y no supervivientes (AUC: 0.941 [0.870-1.000], p < 0.001; AUC: 0.747 [0.593-0.900], p = 0.025; AUC: 0.724 [0.548-0.900], p = 0.042). CONCLUSIONES: Un valor bajo de CLP se puede utilizar como marcador para evaluar la mortalidad y la gravedad de la enfermedad en pacientes con GF.

Prognostic role of preoperative lymphocyte/C-reactive protein associated with upper gastrointestinal cancer: a meta-analysis.

Purpose: The lymphocyte/C-reactive protein (LCR) is a novel immunoinflammatory score and prognostic marker, but the relationship between lymphocyte/C-reactive proteins and clinical outcomes in patients with upper gastrointestinal cancers remains controversial. This study aimed to evaluate the relationship between LCR and the prognosis of upper gastrointestinal cancer by systematic evaluation and meta-analysis. Methods: We systematically searched PubMed, EMBASE, Cochrane, and Web of Science databases to obtain related studies on the relationship between LCR and esophageal cancer (EC), gastric cancer (GC), and esophagogastric junction cancers (EGJ), and used hazard ratio (HR), 95% confidence interval (95%CI) to evaluate the prognostic value of LCR. Outcome measures included overall survival (OS) and disease-free survival (DFS). Results: Eight retrospective cohort studies with 2838 patients were included. Meta-analysis showed that patients with low LCR cancers had poor overall survival OS and disease-free survival DFS (HR=2.18, 95%CI=1.87-2.55; HR=1.88, 95%CI=1.56-2.26). Subgroup analysis based on cancer type, treatment modality, gender, T stage, TNM stage, country, and LCR threshold showed that lower LCR levels were all associated with worse OS and DFS (P<0.05). Conclusion: The LCR can be used as a prognostic marker for patients with upper gastrointestinal cancers, and patients with a lower LCR may have a poor prognosis. Due to the limited number of studies included and mostly retrospective studies, the above findings require validation by more high-quality studies.

Prognostic value of lymphocyte-C-reactive protein ratio in patients with liver cancer: a meta-analysis.

Background: The impact of lymphocyte-C-reactive protein ratio (LCR) on clinical outcomes has been reported in liver cancer such as hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), but the results remain inconsistent. Methods: We searched PubMed, Scopus, Web of Science, Embase and Cochrane Library databases for relevant studies evaluating the association of LCR with survival outcomes and clinicopathological parameters. Results: Eight studies with 4316 patients were included in this meta-analysis. Low LCR was significantly associated with poor overall survival, disease-free survival/relapse-free survival and disease progression clinicopathological parameters in patients with HCC or ICC. Conclusion: Low pretreatment LCR was an adverse prognostic indicator in patients with HCC or ICC. In addition, it was correlated with clinicopathological parameters indicating a higher stage of malignancy.

Prognostic Impact of Lymphocyte-C-Reactive Protein Ratio in Patients Who Underwent Surgical Resection for Hepatocellular Carcinoma.

BACKGROUND: Systemic inflammation-related factors, either independently or in combination, are recognized as prognostic factors for various cancers. The ratio of lymphocyte count to C-reactive protein concentration (lymphocyte-CRP ratio; LCR) is a recently identified prognostic marker for several cancers. Here, we examined the prognostic value of the LCR in patients with hepatocellular carcinoma (HCC). METHODS: This was a single-center retrospective study of patients who underwent surgical resection for HCC between 2004 and 2017. Patients were divided into high- and low-LCR status groups, and the relationships between LCR status, prognosis, and other clinicopathological characteristics were analyzed. RESULTS: A total of 454 patients with HCC were enrolled and assigned to the high- (n=245) or low- (n=209) LCR groups. Compared with the high-LCR group, patients in the low-LCR group had a significantly lower serum albumin level (median 4.1 vs. 3.9 g/dL, P <0.0001), lower platelet count (median 14.0 vs. 12.0 ×104/µL, P=0.0468), lower prothrombin time (median 93.2 vs. 89.6 %, P=0.0006), and larger tumor size (median 2.3 vs. 2.5 cm, P=0.0056). Patients with low-LCR status had significantly worse outcomes of overall survival and disease-free survival than patients with high-LCR status (P=0.0003 and P=0.0069, respectively). Low-LCR status was significantly associated with worse overall survival in multivariate analysis (hazard ratio 1.57, 95% confidence interval 1.14-2.17, P=0.0058). CONCLUSIONS: Low-LCR status may predict worse outcomes in patients with HCC. Measurement of LCR is routine and can easily be applied for risk stratification in the assessment of patients with HCC.

Prognostic Role of Lymphocyte-C-Reactive Protein Ratio in Colorectal Cancer: A Systematic Review and Meta Analysis.

Introduction: The lymphocyte-C-reactive protein ratio (LCR) is a new immunoinflammatory score and prognostic marker, but the relationship between this index and the prognosis of colorectal cancer patients remains controversial.Therefore, aim of the study was to assess the relationship between LCR and prognosis for colorectal cancer patients through a systematic evaluation and meta-analysis. Methods: We systematically searched PubMed, EMBASE, Web of Science, and Cochrane Library databases for randomized controlled studies and observational studies on the relationship between LCR and prognosis of colorectal cancer patients, all searched from the date of database creation to January 6, 2022.Our primary endpoints observed were overall survival (OS) and disease-free survival (DFS) of colorectal cancer patients, and secondary observables were basic characteristics of included studies, such as country, study duration, sample size, LCR threshold, and pathological characteristics of patients in each study, such as degree of differentiation, gender, tumor location, T stage, and lymphatic metastasis. Results: A total of 10 case-control studies including 7068 patients were included. Meta-analysis results showed that overall survival (OS) and disease-free survival (DFS) were worse in colorectal cancer patients with lower levels of LCR (HR=0.44, 95% CI=0.38-0.52, P<0.001; HR=0.56, 95% CI=0.41-0.76, P< 0.001).Subgroup analysis based on country, study length, sample size, and LCR threshold showed that lower levels of LCR were all associated with poorer OS (P < 0.05). Regarding pathological characteristics, patients in the low LCR group were generally poorly differentiated (OR=1.79, 95% CI=1.55-2.07, P<0.001), while there was no significant relationship with gender, tumor location, T stage, and lymphatic metastasis (P>0.05). Discussion/Conclusion: LCR can be used as a prognostic marker for colorectal cancer patients, and patients with lower levels of LCR may have a poor prognosis. Due to the limitation of the number and quality of the included studies, the above findings need to be validated by more high-quality studies.

Lymphocyte-C-reactive protein ratio can differentiate disease severity of COVID-19 patients and serve as an assistant screening tool for hospital and ICU admission.

In this study, we aimed to explore whether lymphocyte-C-reactive protein ratio (LCR) can differentiate disease severity of coronavirus disease 2019 (COVID-19) patients and its value as an assistant screening tool for admission to hospital and intensive care unit (ICU). A total of 184 adult COVID-19 patients from the COVID-19 Treatment Center in Heilongjiang Province at the First Affiliated Hospital of Harbin Medical University between January 2020 and March 2021 were included in this study. Patients were divided into asymptomatic infection group, mild group, moderate group, severe group, and critical group according to the Diagnosis and Treatment of New Coronavirus Pneumonia (ninth edition). Demographic and clinical data including gender, age, comorbidities, severity of COVID-19, white blood cell count (WBC), neutrophil proportion (NEUT%), lymphocyte count (LYMPH), lymphocyte percentage (LYM%), red blood cell distribution width (RDW), platelet (PLT), C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum creatinine (SCr), albumin (ALB), total bilirubin (TB), direct bilirubin (DBIL), indirect bilirubin (IBIL), and D-dimer were obtained and collated from medical records at admission, from which sequential organ failure assessment (SOFA) score and LCR were calculated, and all the above indicators were compared among the groups. Multiple clinical parameters, including LYMPH, CRP, and LCR, showed significant differences among the groups. The related factors to classify COVID-19 patients into moderate, severe, and critical groups included age, number of comorbidities, WBC, LCR, and AST. Among these factors, the number of comorbidities showed the greatest effect, and only WBC and LCR were protective factors. The area under the receiver operating characteristic (ROC) curve of LCR to classify COVID-19 patients into moderate, severe, and critical groups was 0.176. The cutoff value of LCR and the sensitivity and specificity of the ROC curve were 1,780.7050 and 84.6% and 66.2%, respectively. The related factors to classify COVID-19 patients into severe and critical groups included the number of comorbidities, PLT, LCR, and SOFA score. Among these factors, SOFA score showed the greatest effect, and LCR was the only protective factor. The area under the ROC curve of LCR to classify COVID-19 patients into severe and critical groups was 0.106. The cutoff value of LCR and the sensitivity and specificity of the ROC curve were 571.2200 and 81.3% and 90.0%, respectively. In summary, LCR can differentiate disease severity of COVID-19 patients and serve as a simple and objective assistant screening tool for hospital and ICU admission.

Prognostic Potential of Lymphocyte-C-Reactive Protein Ratio in Patients with Rectal Cancer Receiving Preoperative Chemoradiotherapy.

PURPOSE: The systemic inflammatory response is attracting increasing attention as a predictive biomarker for oncological outcome in patients with colorectal cancer. This study is aimed at verifying if the lymphocyte-C-reactive protein (CRP) ratio (LCR) could be used as a predictor of oncological outcome in patients with rectal cancer (RC) receiving preoperative chemoradiotherapy (CRT). METHODS: We analyzed data for 86 patients with RC who received preoperative CRT followed by total mesorectal excision at our institution. A ratio of 6000 was used as the cut-off value for LCR for further analysis. RESULTS: The post-CRT LCR was significantly lower than the pre-CRT LCR in patients with RC. Although post-CRT LCR status was not significantly correlated with overall survival (OS), low pre-CRT LCR was significantly associated with shorter recurrence-free survival (RFS: p = 0.02) and OS (p = 0.017) in this population and was an independent prognostic factor for both RFS and OS (hazard ratio (HR) 3.19, 95% confidence interval (CI) 1.33-7.66, p = 0.009; HR 2.83, 95%CI 1.14-7.01, p = 0.025, respectively). Furthermore, low pre-CRT LCR was a stronger indicator of early recurrence (p = 0.001) and poor prognosis (p = 0.025) in RC patients without pathological lymph node metastasis compared with patients with pathological lymph node metastasis, and prognostic potential of pre-CRT LCR was clearly revealed especially RC patients receiving long-course CRT. CONCLUSIONS: Assessment of pretreatment LCR status might aid decision-making regarding postoperative treatment strategies in patients with RC receiving CRT followed by potentially curative resection.

Prognostic Value of Lymphocyte-C-Reactive Protein Ratio in Patients Undergoing Radical Cystectomy for Bladder Cancer: A Population-Based Study.

PURPOSE: This study aimed to assess the prognostic value of the lymphocyte-C-reactive protein ratio (LCR) in patients with bladder cancer (BCa) who underwent radical cystectomy (RC). MATERIALS AND METHODS: BCa patients between 2009 and 2018 were retrieved from our medical center. The predictive value of LCR on survival of BCa patients was evaluated through the Kaplan-Meier survival and receiver operating characteristic (ROC) curves. The multivariate Cox regression results were used for conducting the nomogram, which were further verified by ROC, decision curve analysis (DCA), and calibration curves. Propensity score matching (PSM) was performed to validate our findings. RESULTS: A total of 201 BCa patients who received RC were included in this study, with 62 (30.8%) patients in the low LCR group and 139 (69.2%) in the high LCR group. Multivariate analysis results revealed that the high LCR group was significantly related to better prognosis and functioned as a prognostic biomarker for overall survival (OS) [hazard ratio (HR) = 0.41, 95% CI, 0.26-0.66; p < 0.001] and disease-free survival (DFS) [HR = 0.40, 95% CI, 0.26-0.66; p < 0.001]. The nomogram processed better predictive capability and accuracy than TNM stage from ROC results (AUC = 0.754 vs. AUC = 0.715), with the confirmation of calibration curves and DCA. The result of PSM confirmed that LCR was significantly correlated with OS and DFS. CONCLUSION: Our finding demonstrates that LCR is a novel, convenient, and effective predictor that may provide vital assistance for clinical decision and individualized therapy in BCa patients after RC.
